焦化场地多环芳烃(PAHs)修复技术研究进展
|
Abstract:
我国是一个焦炭生产大国，焦化过程中产生的废气、废水和固体废物含有多种有害物质，最主要的是多环芳烃(PAHs)。PAHs具有较高的毒性和持久性，对环境和人体健康造成潜在风险。本文通过对国内外PAHs各修复技术的机理及过程，及修复技术使用时的局限性进行总结分析，并对未来PAHs修复技术进一步的探索方向进行展望。这为后续开展PAHs修复技术的研究提供参考和借鉴。
China is a major producer of coke, and the emissions from coking processes contain various harmful substances, with polycyclic aromatic hydrocarbons (PAHs) being the most significant. PAHs are highly toxic and persistent, posing potential risks to the environment and human health. This article provides a summary and analysis of the mechanisms and processes of various remediation technologies for PAHs, both domestically and internationally. It also discusses the limitations of these techniques and provides prospects for future exploration in PAHs remediation technologies. This serves as a reference for future research on PAHs remediation.
